lCE-CREEPER.

SPECIFICATION forming part of Letters I atent No. 767,565, dated August 16, 1904..

Application filed August 31, 1903.

To all whom it may concern/.2

Be it known that I, CARL F. JoLITZ, a citizen of the United States, residing at Pine Island, in the county of Goodhue and State of Minnesota, have invented a new and useful Ice- Creeper, of which the following is a specification.

This invention relates to boots and shoes, and particularly to the manner of applying antislipping devices to rubber soles and heels.

Owing to the consistency of the rubber, the ordinary fastening devices, such as screws and the various styles of clamps, cannot be advantageously employed in connection with the antislipping devices as applied to rubbers, as the rubber is not sufficiently rigid to retain the fastening devices.

It is particularly the. object of this invention to construct an antislipping device which will be inexpensive and easy to apply to the shoe and to provide an efficient means for fastening the device to the shoe.

With these and other objects in view the invention consists in certain'novel features of construction, which will be specifically set forth in the following description, reference being had to the accompanying drawings, in which- Figure l is a perspective view of the blank for the preferred form of the device. Fig. 2 is a perspective view of the device with the calks bent up. Fig. 3 is a sectional view through a portion of a shoe and an antislipping device. Fig. 4 represents a perspective view of a slightly-modified form of antislipping device. Fig. 5 represents a detail sectional View.

The preferred form of the invention is illustrated as comprising two limbs l and 2, terminally connected by an intermediate'and curved portion 3, resembling in form a horseshoe, having terminal calks 4 and 5 and an intermediate calk 6. In practice this form Serial No. 171,450. (No model.)

of the antislipping device will be die-struck of a single piece of metal and will have the calks bent by a suitable former so as to have them outstanding for engagement with the surface.

The means of fastening the device to the heel of the shoe or boot consists of a head or plate 10, with integral depending shanks 10, adapted for insertion into the antislipping device, and the shoe will be clamped between the antislipping device and the head or plate, so that there will be no danger of the fasteners pulling through. Owing to the peculiar formation of the shanks or integral projections 10 and by reason of their being of no greater diameter than the openings in the calk-carrying plate, said plate can be moved upon the shanks so as to firmly secure the shoe-heel between them, and the rivet-heads may then be provided by upsetting the terminals of the shanks.

In the modified form of antislipping device (illustrated in Fig. 4) the rear calk is dispensed with and in its stead two spurs l1 and 12 are employed, which serve to prevent any displacement or slipping of the shoe.

I claim- In an antislipping device, two members, one of which comprises a plate having projections and openings and the other member comprising a plate having depending integral shanks to enter the openings in the firstmentioned plate, the said first mentioned plate being free for uninterrupted clamping movement on the shanks, and upsettable terminals on the shanks to secure the two plates together.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

CARL F. J OLITZ.
